An automobile has a total mass of 1100 kg. It accelerates from rest to 69 km/h in 12 s. Assume each wheel is a uniform 23 kg disk. Find, for the end of the 12 s interval, (a) the rotational kinetic energy of each wheel about its axle, (b) the total kinetic energy of each wheel, and (c) the total kinetic energy of the automobile.

A car wheel has a mass of 30kg and a radius of 45.0 cm. This happens to be a "spinner" which a thin, solid disk of mass 10kg and a radius of 30 cm on the inside of the wheel. If the car was travelling at 9 m/s, what will be the angular velocity of the "spinner" in the center of the wheel when the car stops? (HINT: assume the car wheel is a hollow cylinder)

You throw a frisbee of mass m = 0.5 kg, and radius
r = 0.1 meters, off of a hill, with initial translational
speed of v0 = 5 m/s, from a height of
h0 = 3 meters. The tangential speed of the edge
of the frisbee is equal to the initial translational speed, and
doesn't change as it travels through the air. Treat the frisbee as
a solid disk, and ignore air resistance.

A 1200 kg car traveling at 60 mph quickly brakes to a halt. The kinetic energy of the car is converted to thermal energy of the disk brakes. The brake disks (one per wheel) are iron disks with a mass of 4.0 kg. Estimate the temperature rise in each disk as the car stops. Express your answer using two significant figures.
